Abstract

PROBLEM TO BE SOLVED: To improve the relation between a function to vary probability and a time shortening function to enhance fun. SOLUTION: When the large winning patterns among probability patterns are led out in the respective special pattern display areas 50a-50c of an LCD 32a, probability improving period is generated, the period continues until special patterns vary for 50 times and a high probability state is attained. After they vary for 50 times, the period ends. In the meantime, when the probability improving period starts, a time shortening period is also occured, the period continues until the special patterns vary for 100 times and a time shortening operation is executed. After they vary for 100 times, the period ends. In the case that the large winning patterns among probability variation patterns are displayed again during the probability improving period or the time shortening period, a probability variation counter G or a time shortening variation counter H is reset and counting can be performed from the beginning. In the case that a large winning state is generated during the probability improving period and the time shortening period, a large winning operation is given priority and a high probability operation and the time shortening operation executed in the period can be put in a stop state.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game machine, and more particularly, to a game machine having a probability varying function and a time shortening function.

[0002]

2. Description of the Related Art Conventionally, in a gaming machine equipped with a variable display device for displaying a special symbol, a variable display game on the variable display device is started by winning a special symbol starting port, and after a lapse of a predetermined time. When the variably displayed symbol is stopped and the stopped symbol is in a stop display mode indicating the occurrence of a big hit state such as a zoro eye, a state in which a game ball can be easily obtained by opening operation of a variable winning device or the like. Generally, a big hit state (special game state) is generated.

In particular, recently, there have been many gaming machines that use a liquid crystal display device or a CRT display device as a variable display device and perform variable display games by displaying a plurality of identification information as images.
When a big hit state occurs in a conventional gaming machine as described above, the stop symbol, the number of rounds (the number of continuations), or the count number (variation per round) when the big hit state occurs is displayed on the variable display device of the gaming machine. The effect display in the state of the big hit has been performed by displaying the number of winnings in the winning device or the like and displaying the action by the character (for example, displaying that the character travels the world).

Further, recently, in this type of pachinko game machine, a stop display mode when a big hit occurs, for example,
In the case of a specific symbol (probability changing symbol) such as 1, 3, 5, 7, etc. (for example, “3, 3, 3”, “7,
7, 7 "), after the end of the big hit game state, until the next big hit occurs a predetermined number of times (for example, once or twice).
There is also known a pachinko gaming machine that generates a probability variation state in which the probability of a big hit in a variable display game of a special symbol is changed to a high probability state.

Similarly, a special symbol starting port is provided with a normal electric accessory, and a normal symbol for determining the opening / closing of the ordinary electric accessory is provided. Until the next big hit occurs a predetermined number of times (once or twice), the probability of a normal symbol is set to a high probability state and the ordinary electric accessory is frequently opened, thereby increasing the winning rate to the starting opening. Gaming machines having a function of raising the jackpot to accelerate the occurrence of a big hit are also known.

[0006] When the probability fluctuation state as described above occurs, if a big hit occurs again with a specific probability fluctuation symbol during the probability fluctuation state, the probability fluctuation state is restarted from the initial state. In many cases, a function for continuously updating the probability fluctuation state is also provided.

Further, the fluctuation time of the ordinary symbol is made shorter than that in the normal game state (for example, from 30 seconds to 5 seconds), and the opening pattern of the ordinary electric accessory when the ordinary symbol hits is changed (for example, With the opening time of 0.5 seconds and the opening of 3 times of 1.5 seconds), the opportunity to open the electric accessory is increased and the winning rate at the starting opening is increased. A gaming machine is also considered. In this case, for example, after the big hit is completed, the time reduction game of the ordinary symbol is generated until the special symbol fluctuates 50 times.

[0008]

However, the conventional relationship between the probability variation function and the time reduction function is that, for example, since the number of times of the special symbol variation is set to the same predetermined number for both the probability variation and the time reduction, When the fluctuation ends, the time saving function ends at the same time. Therefore, in a situation where the high-probability state or the time-saving state ends immediately, such as when the number of times is small, the interest of the player may be lost.
Furthermore, since the timings of the probability variation function and the time reduction function are synchronized each time, it is not possible to perform a continuous big hit effect sufficiently, and the interest of the game is insufficient.

Therefore, an object of the present invention is to improve the relationship between the probability variation function and the time reduction function, and to provide a gaming machine capable of improving the interest.

[0010]

In order to solve the above-mentioned problems, a game machine according to the first aspect of the present invention has a starting means for causing a fluctuation stop of a symbol, and whether or not to execute a game advantageous to a player. The symbol is variably displayed due to the operation of the starting means and the condition satisfaction determining means for determining whether the condition is satisfied, and a game advantageous to the player is executed when the condition is satisfied by the condition satisfaction determining means. An informative symbol display means for displaying a disadvantageous informative symbol indicating that an advantageous game is not executed if the conditions are not satisfied, and a game advantageous to the player when stopped and displayed with the advantageous informative symbol After the has been executed, and in a predetermined case, the probability improvement period to improve the probability that the symbol is displayed in the advantageous notification symbol,
Thereafter, the probability varying means for reducing the probability and, when stopped and displayed in the advantageous notification symbol, execute a game advantageous to the player, and thereafter reduce the symbol changing time and change the starting means to the player. A gaming machine comprising: a profit state providing unit that sets the operating state to be advantageous to the gaming machine, wherein the probability improvement period by the probability varying unit and the profit providing period by the profit state providing unit are different. is there.

The ball game machine according to claim 1, which has the above-described configuration, has a configuration that has not been conventionally provided by differentiating the probability improvement period by the probability varying means and the profit provision period by the profit state providing means. A game can be realized, and the above problem can be suitably solved. In addition, even after the end of the probability improvement period, by providing the privilege of shortening the time, the player is not bored. On the other hand, even after the end of the short period of time, by providing the benefit of the probability improvement period, the player is not bored. effective.

Here, a specific description will be given of the configuration of "difference between the probability improving period by the probability varying means and the profit providing period by the profit state providing means".

Here, the "starting means" includes a starting port (prize opening port, entrance port, ordinary electric accessory, etc.) or a starting gate. A game ball enters the starting port or enters the starting gate. The symbol stops fluctuating due to the passing of the game ball. The “profit state giving means” sets “the starting means to be in an advantageous operating state for the player”. Specifically, the change time of a symbol (for example, a normal symbol) displayed on another display device is set to For example, it is possible to shorten the number of times the starting means operates, or to increase the number of operations of the starting means or extend the operation period.

[0014] The "condition establishment determining means for determining whether or not to execute a game advantageous to the player" is, for example, a case where a game ball fired on the game board enters a specific entrance or passes through a specific entrance. In accordance with the random number value extracted based on the timing of passing through the mouth, it is determined whether or not to make the game content advantageous to the player. Here, the “advantageous game” is a state in which the player is directly in an advantageous state by the value of the random number extracted due to the timing of entering a specific entrance or passing through a specific passage. In addition to this, a predetermined winning opening (entrance opening) is opened by a value of a random number extracted due to a timing at which the ball enters a specific entrance or passes through a specific passage. A so-called third state that, when a game ball passes through a specific area in an open specific winning opening, is in a state advantageous to the player.
Seed game machine (rights), arrange ball game machine, etc.
It also includes game contents such as gaming machines that are appropriately combined with the first to third kind of pachinko machines and the third kind of pachinko machines and which are indirectly advantageous to the player in the gaming machine. It should be noted that the configuration may be such that a game ball as a prize ball is paid out upon entry of a ball (in this case, it is often called a “winning opening”), or a configuration may not be provided.

The "notification symbol display means" is a game content that is advantageous to the player, for example, after a symbol on the screen is variably displayed each time it is determined whether or not the game content is advantageous to the player. Any symbol may be used as long as it is controlled so as to be statically displayed with an advantageous information symbol indicating whether or not the symbol is displayed. The symbol indicating that the content of the game is advantageous to the player is displayed with the same three-digit symbol such as "777". A symbol to win, a symbol in which the main character (hero) wins in martial arts, a symbol in which the main character wins in a race, a symbol in which the main character wins or a symbol in a ball game, a symbol in which the main character discovers a treasure in an adventure story, The symbol which shows a happy state, such as a main character or people related to a main character, receiving profit etc. can be considered. Examples of the “unfavorable information symbol” include a symbol displaying a three-digit non-identical symbol such as “769”, a symbol indicating that the protagonist is unhappy, and the like. The "notification symbol display means" includes not only screens of a CRT and a liquid crystal display but also a display unit of a device capable of displaying the symbol such as a dot matrix display and a 7-segment LED.

The processing executed by the 8-bit one-chip microcomputer (hereinafter simply referred to as "microcomputer") in the main control board 30 of the pachinko machine 10 having the above-described circuit configuration will be described with reference to the flowchart shown in FIG. To The flowchart shown in FIG.
Represents the main processing executed by the microcomputer, and is a processing periodically executed by a hard interrupt every about 2 ms. In the present embodiment, steps S10 to S
Each of the processes up to 60 is a process executed only once in the interrupt process, and is referred to as "main process", and steps S65 and S70 are repeatedly executed as long as time permits, within the time remaining after executing the main process. Is referred to as “residual processing”.

When a hardware interrupt is executed by the microcomputer, it is first determined whether or not the interrupt is a normal interrupt (step S10). This determination process is performed by the RA as a memory.
This is performed by determining whether or not the value of the predetermined area of M is a predetermined value. When the processing executed by the microcomputer shifts to this processing, it is determined whether the normal processing may be performed. It is for. In unusual cases,
Runaway of the microcomputer due to noise or the like can be considered when the power is turned on, but runaway of the microcomputer can be considered to be almost non-existent due to the improvement of technology in recent years. When the power is turned on, the value of the predetermined area of the RAM is different from the predetermined value. If it is determined that the symbol is not normal, a predetermined value is written to a predetermined area of the memory, and each initial value is written to a work area of the memory, such as a special symbol and a normal symbol as an initial symbol. Step S15), proceed to residual processing.

When a positive determination is made, the initial random number updating process is executed (step S20). This processing is performed every time this processing is performed on the value of the initial random number.
This is an incrementing process of incrementing the initial random number value by one, and adding +1 to the value of the initial random number before the execution of this process. ”, And 3 from“ 0 ”to“ 299 ”
00 integers are repeatedly created in ascending order.

The success / failure random number update process (step S25) subsequent to step S20 is an increment process of incrementing by +1 each time the process is executed, similarly to the initial random number update process.
In the next process, when the value reaches the maximum value “299”, the value of the initial random number at that time is set as an initial value (hereinafter, referred to as “update initial value”), and the process of adding +1 to each interrupt is continued. When the value reaches a value "1" smaller than the update initial value (hereinafter, referred to as "update maximum value"), in the next process, the value of the initial random number at that time is further set as an initial value and 300 from "0" to "299". Repeatedly create integer values.

That is, the value of +1 is incremented every interrupt processing, and the element constituting the random number is set to an integer value from "0" to "299", which is not different from the initial random number at all. Then, in the next interrupt processing, the update initial value at that time is used as an initial value, and +1 is added for each interrupt until the update maximum value is reached, and the next update initial value is used as the initial value. As a result, the pass / fail random number is set to 300 integer values from “0” to “299” in the elements constituting the random number, and is incremented by one for each interruption process. Since the value is changed to the value determined by the initial random number at that time, the value of the pass / fail random number can be made unpredictable. Also, the components of the random number determined by the update initial value and the update maximum value do not change at all from the same 300 integer values of “0” to “299” as the conventional random number, so the elements constituting the random number Has a uniform appearance rate.

The big hit symbol random number updating process (step S3)
0) is configured as a counter for repeatedly creating 15 integers from “0” to “14”, and is incremented by 1 every time this processing is performed, and returns to the initial value “0” when exceeding the maximum value. The fifteen random numbers “0” to “14” are the same three digits “111”, “222”, “333”, and “44” displayed on the screen.
4 "," 555 "," 666 "," 777 "," 88 "
8 "," 999 ", [AAA]," BBB "," CC
C "," DDD "," EEE ", and" FFF ".

Missing symbol random number update processing (step S35)
Is composed of a random number for a left symbol, a random number for a medium symbol, and a random number for a right symbol, and is used as a missing symbol when no big hit occurs. The left symbol random number is configured as a counter that repeatedly generates fifteen integers from “0” to “14”, and is incremented by one every time this processing is performed, and returns to the initial value “0” when exceeding the maximum value. The medium symbol random number is configured as a counter that repeatedly generates fifteen integers from "0" to "14". When the left symbol random number returns to "0", it is incremented by +1 for each process and exceeds the maximum value. Return to "0". The random number for the right symbol is "0" to "1".
It is configured as a counter that repeatedly generates 15 integers of "4". When the medium symbol random number returns to "0", it is incremented by 1 every time this processing is performed, and when the random number exceeds the maximum value, it returns to "0".

Normal symbol random number update processing (step S40)
Is configured as a counter for repeatedly creating seven integers from “0” to “6”, and is incremented by one in this processing, and returns to the initial value “0” when the maximum value is exceeded.

The above-described random number updating processing (step S20)
Through S40), the initial random number, the pass / fail random number, the jackpot symbol random number, the off symbol random number, and the ordinary symbol random number are updated. In the subsequent processing (step S45), the random number is provided to the pachinko machine 10 and connected to the main control board 30. Input processing of each switch is executed. In the present embodiment, the full tank switch 43, the supply switch 44, and the touch switch 24 described above are used.
a, first-type starting port switch 36a, V switch 40a,
Count switch 40b, normal symbol operation switch 38a
And 39a, and a process of checking the operation status of each switch such as a prize detecting switch (not shown) provided in the other prize port. When there is an input to the first-type starting port switch 36a by this input processing, it means that the game ball has won the ordinary electric accessory 36 as a starting port,
The value of the random number at the time of this interrupt processing is extracted and compared with the determination value.

The pachinko machine 10 of the present embodiment is configured as a probability varying machine, and at the time of normal probability, the judgment value is "1".
When the probability is high, "1", "3", "5",
"7" and "9". As described above, the appearance rate of each of the 300 integer values of “0” to “299” constituting the random number is uniform, and the game ball serves as the starting port.
The value of the random number extracted at the timing of winning 6 is
When compared with 2 ms, which is the minute time of the hard interrupt, the winning timing cannot be adjusted in minute time units, so it becomes a value extracted at random, and the pass / fail random number functions as a perfect random number. Therefore, the probability that the value of the extracted success / failure random number matches the success / failure determination value and becomes a big hit is 1/300 at the time of the normal probability and 1/60 (= 5 /
300). The probability that this big hit occurs is shifted from the low probability state to the high probability state in the present embodiment,
The value of the above-mentioned jackpot symbol random number in the interrupt processing at the time of the jackpot occurrence is “1”, “3”, “5”, “7”,
This is the case of "9", "11", and "13" (hereinafter, referred to as "high-probability random number"), and shifts to high probability at a probability of 7/15 when a big hit occurs. Then, during the high probability, if the value of the big hit symbol random number when the big hit is generated again is the high probability random value, the high probability state continues. That is, there is a possibility that the high probability will continue at a probability of 7/15 every time the state becomes the high probability state once.

Subsequently, a hit / fail determination process (step S50) for determining whether or not a big hit has occurred is performed. When the success / failure determination process (step S50) ends, an image output process (step S55) is subsequently performed. This image output processing (step S55) will be described in detail with reference to FIG. The command code shown in FIG. 7 is a code transmitted from the main control board 30 to the symbol control board 32b of the special symbol display device 32.

As shown in FIG. 7, the transmission command codes of the main control board 30 and the symbol control board 32b of this embodiment are: 1. When power is turned on. 2. Customer waiting demo; 3. While the design is changing. 4. At the start of the jackpot During the jackpot, 6. At the end of the jackpot, 7. At the time of abnormal operation, it can be roughly classified into seven types.

1. Power-on command The power-on command is a command code transmitted from the main control board 30 to the symbol control board 32b when the pachinko machine 10 is powered on, and is a two-byte instruction of an operation number 10H and an identification number 01H. It is configured. When the symbol control board 32b receives this command, a demo screen at power-on is displayed on the screen of the LCD 32a according to the control program written in the ROM.

2. Customer Waiting Demo The customer waiting demonstration command is transmitted after the power-on demonstration screen is completed or when it is determined that the player has not touched the firing handle 24 for a predetermined time (usually about 3 minutes). It is a command, and is composed of a 2-byte instruction with an operation number 20H and an identification number 01H. When the symbol control board 32b receives this command, it displays a customer waiting demonstration screen on the screen of the LCD 32a according to the control program written in the ROM. For example, the variation patterns of the special symbols which are variably displayed on the special symbol display areas 50a to 50c shown in FIG. 6 are sequentially displayed. Also, the hold storage display unit 51
a to 51d are sequentially lit and displayed. At this time, the background screen 5
On 2, a background image and a character corresponding to each variation pattern are displayed. The customer waiting demonstration screen displays all the variation patterns in order until the player operates the firing handle 24, makes one round, and then repeatedly displays it. Note that whether or not the player is touching the firing handle 24 can be detected by inputting the touch switch 24a. In the present embodiment, since the input of the touch switch 24a is input to the main control board 30, the detection between the main control board 30 and the emission control board 33 is performed while the communication between the main control board 30 and the emission control board 33 is one-way communication. Is possible. of course,
On / off information of the touch switch 24 a is transmitted from the main control board 30 to the emission control board 33. The input of the touch switch 24a is inputted to the launch control board 33, and there is no prize in any or all of the prize ports for a predetermined time, or a switch is provided in the out port 41 of the game board 22, and the switch is provided. It may be configured to determine that the player is not executing a game by not turning on for a predetermined time.

3. The symbol change command is generated by the main control board 30 during the symbol change, and the symbol control board 32b is transmitted from the main control board 30 during the special symbol change.
The command is transmitted to (1) as shown in FIG.
Fluctuating time code, (2) left stationary symbol designating code,
The command codes are classified into four types of command codes (3) middle stationary design designation code, and (4) right still design designation code (hereinafter, these four command codes may be collectively referred to as "image display command"). You.

(1) Fluctuating Time Code The fluctuating time code is composed of 30 types of 1-byte instructions having an operation number of 30H and 30 types of 1-byte instructions of 01H to 1EH as identification numbers, and 30 types of 2-byte instructions. 30 types of 1-byte instructions are from 5 seconds to 35 per second.
It represents 30 types of time in seconds.

(2) Left stationary symbol designating code The left stationary symbol designating code is an instruction code consisting of an operation number of 31H and 15 types of identification numbers of 01H to 0FH. When the identification number is 01H, a left stationary symbol is designated. "0", "1" for 02H, "2" for 03H, "3" for 04H, 05
"4" for H, "5" for 06H, "6" for 07H, "7" for 08H, "8" for 09H, 0AH
"9" for 0B, "A" for 0BH, "B" for 0CH, "C" for 0DH, "D" for 0EH, 0FH
In this case, the character "E" is displayed in the special symbol display area 50a as a special symbol.

(3) Middle stationary symbol designation code The middle stationary symbol designation code is an instruction code consisting of an operation number of 32H and 15 types of identification numbers of 01H to 0FH, and the identification number is the same as the left stationary symbol designation code. It has the same meaning as the identification number, and is used for displaying the designated character as a special symbol in the special symbol display area 50b.

(4) Right stationary symbol designation code The right stationary symbol designation code is an instruction code consisting of an operation number of 33H and 15 types of identification numbers of 01H to 0FH, and the identification number is the same as the left stationary symbol designation code. It has the same meaning as the identification number, and is used to display a character designated by each as a special symbol in the special symbol display area 50c.

The variable time code, the left, middle and right stationary symbol designating codes are used for symbol control almost simultaneously by two bytes each time a game ball fired on the game board 22 wins the ordinary electric accessory 36 as a starting port. This is a command code transmitted to the board 32b, and its content is determined as follows.

As described above, the game ball is usually the electric accessory 3.
When the player wins 6, the value of the random number at the time, the value of the jackpot symbol random number, and the value of the out-of-point symbol random number are respectively extracted. The extracted random number value is compared with the randomness value “1” at the time of normal probability, and the randomness value “1”, “3”,
Compared with “5”, “7”, “9”, and “11”, if they match, a big hit occurs, and if they do not match, it is off. When a big hit occurs, the random number value of the extracted big hit symbol is incremented by +1.
Then, this value is used as the identification number of the left, middle, and right still symbol designating code. That is, the identification numbers of the left, middle, and right stationary symbol designating codes are the same. If they do n’t match,
A value obtained by adding +1 to each of the left symbol, the middle symbol, and the right symbol random number of the extracted off symbol random numbers is used as the identification number of the left, middle, and right stationary symbol designating code. At this time, if the three identification numbers coincide with each other by accident, a process is performed to make the value of the identification number of the right stationary symbol designating code differ by “1”. The above-mentioned variable time code is a large value when the identification numbers of the left, middle and right stationary design designation codes all match, and is an intermediate value when the identification numbers of the left and middle stationary design designation codes match even if they do not all match. If they do not match at all, they are assigned to smaller values.

The processing performed by the symbol control board 32b when receiving the image display command including the four command codes will be described. The details of the reach and the control of the reach determination probability will be described later. When the microcomputer of the symbol control board 32b receives the image display command, it executes a process of creating a variation pattern of a special symbol from the received variation time and the identification numbers of the left, middle, and right stationary symbol designating codes. As shown in FIG. 8, a table corresponding to a combination of each value of the received image display command is written in the ROM of the symbol control board 32b. Symbol control board 32
The microcomputer b reads ROM from the received image display command.
Is read out to create a special symbol variation pattern. This variation pattern is created as follows.

The microcomputer determines from the identification numbers of the received left, middle, and right stationary symbol designating codes whether or not the identification numbers of the left and the middle match (that is, whether or not reach), and the normal fluctuation is performed. Or reach fluctuation, and furthermore, in reach fluctuation, it is determined whether or not various fluctuations such as trick fluctuations are performed depending on whether the fluctuation time value is larger or smaller than a predetermined value, and these judgments and fluctuation time are determined. To determine the respective times from the start of the change of the left, middle and right symbols of the special symbol to the standstill. The display data of the background and the character displayed on the background screen 52 is also created according to the special pattern variation pattern created in this manner. When the variation pattern is created, the process of starting the variation of each of the left, middle and right special symbols according to the created variation pattern and executing the process of statically displaying the designated still symbol is performed, and the display control of the background and the character is also performed. Be executed. If a game ball is awarded to the ordinary electric accessory 36 as a starting port during the change of the special symbol, a command code not shown in FIG.
Is transmitted to the symbol control board 32b from the
1a to 51d are lighted and displayed.

4. Big hit start Big hit start demonstration command code is special symbol display area 5
When displaying an image appealing to the player that a big hit has occurred between the time when the big hit operation is started after the left, middle and right special symbols displayed on 0a to 50c display the same symbol. Command used, 40H
And the identification number of 01H. When the symbol control board 32b receives this command code, the LCD
On the screen 32a, characters such as big hits are displayed to display an image that makes the character happy, and a process of outputting a sound effect by the sound control board 35 is performed. At this time, the symbol control board 32b determines from the image display command, that is, whether a big hit has occurred based on whether or not the identification numbers of the received left, middle, and right still symbol designating codes match with each other. When the affirmative judgment is made, the value of the previously stored number of jackpots is incremented by one, and the number of hits is displayed on the background screen 52. This allows the player to be notified of the total number of jackpots that have occurred in the pachinko machine 10 during business hours after opening the pachinko hall.

The symbol control board 32b determines whether the identification numbers of the received left, middle, and right stationary symbol designating codes match from the image display command, and whether or not the probability change flag is set. When the affirmative determination is made that the jackpot is in the high probability, the value of the number of hits in the high probability stored previously is incremented by one, and the number of hits is displayed on the background screen 52. As a result, the number of big hits during the high probability (the so-called “number of consecutive chan”) is notified to the player. The number of jackpots during this high probability is cleared to zero when the high probability continuation is no longer executed,
It will be displayed again when the high probability continuation jackpot occurs again. The symbol control board 32b stores the number of hits during the maximum high probability since opening the pachinko hall during business hours, and updates the value when a large hit occurs during the high probability exceeding the maximum number. The number of big hits during this high probability can be displayed together with the total number of big hits.

5. Jackpot Medium Jackpot Medium command is code before opening, code during opening, 1
It is classified into five command codes of a 0 count winning code, a V passing code, and a round display code. (1) The pre-opening code is composed of an operation number of 50H and an identification number of 01H. When the symbol control board 32b inputs this command code, an image notifying the player that the special winning opening 40 will be opened is displayed on the background screen. The processing displayed on 52 is executed. (2) The open code is composed of an operation number of 50H and an identification number of 02H. When the symbol control board 32b inputs this command code, an image that informs the player that the special winning opening 40 is open is displayed. A process to be displayed on the background screen 52 is executed. (3) 10-count prize code is 50H operation number and 0
The main control board 30 is provided with a count switch 40b for detecting that a game ball has entered the special winning opening 40.
Alternatively, this instruction code is transmitted each time the detection is performed by the V switch 40a. When the symbol control board 32b inputs this command code, the value is incremented and the value is displayed on the background screen 52 each time the command code is input. As a result, every time a game ball wins in the special winning opening 40, the number display from 0 to 10 is displayed on the screen. (4) The V pass code is composed of an operation number of 50H and an identification number of 04H. When the main control board 30 detects that the game ball has passed the special area in the special winning opening 40 by the V switch 40a, this command is issued. Submit the code. When the symbol control board 32b inputs this command code, the character "V" is displayed in a large size on the background screen 52 to inform the player that the special winning opening 40 is closed and then opened again. (5) The round display code is composed of an operation number of 50H and an identification number of 05H.
Transmits this command code each time the device is opened again after the completion of the opening operation. When the symbol control board 32b inputs this command code, the value is incremented and the value is displayed on the background screen 52 each time the command code is input. This allows
The player is notified of the number of times the special winning opening 40 has been opened.

6. Jackpot end The jackpot end command consists of a jackpot end demo code and a high-probability transition code. The jackpot end demo code indicates that the game ball has not passed through the special area when the jackpot operation has ended, that is, when the jackpot 40 has completed the opening operation 16 times, or when the opening has not been continued up to 16 times. This command code is transmitted from time to time, and includes an operation number of 60H and an identification number of 01H. When the symbol control board 32b inputs this command code, a message is displayed to inform the player that the big hit has ended. The high probability transition code is 61
It consists of an operation number of H and identification numbers of 01H to 02H.
When the identification number is 01H, the high-probability state continues, and when the identification number is 02H, the high-probability state does not continue. This high-probability transition code may be configured to be transmitted from the main control board 30 as in the present embodiment,
From the value of the above-described image display command, the symbol control board 32b
May be determined. After the elapse of the probability improvement period, the probability becomes low.

6.1 Time Saving Operation Time saving operation is performed in connection with the high probability period. There are various types of time saving operation, the contents of which are well-known, but an example will be described below. First, the time from the start of the special symbol variation display to the display of the set symbol is reduced. The time is reduced by a plurality of symbols (3 in this example) displayed when the special symbol variation display is stopped.
The time is shortened due to establishment of a predetermined condition such as when a special symbol (probably changing symbol) is a preset special symbol among the special symbols (digits). By reducing the time (hereinafter also referred to as time saving) in this manner, the maximum value of the number of times the special symbol change display is performed within a certain time is increased. Then, the special symbol change display is shortened, so that the special symbol change display can be performed at an early point in time in accordance with the start winning. Therefore, it is possible to avoid a situation in which the special symbol display cannot be promptly activated despite the fact that the ordinary electric accessory (starting opening) 36 is won.

Further, as described above, the time required to change the special symbols is reduced, and the time required for the ordinary symbols displayed on the ordinary symbol display device 37 is also reduced. By shortening the normal symbol variation display, the normal symbol display is activated many times within a certain time. Therefore, the number of operable normal symbol displays per time increases. If the normal symbol variation display is shortened, the number of times the normal symbol hits is increased, thereby increasing the number of times the ordinary electric accessory 36 is activated, and the start winning is easy. By facilitating the winning start in this way,
It is difficult for the player to reduce the number of balls, and a more advantageous game can be played. The relationship between the probability variation and the time saving will be described later in detail.

7. The operation abnormal operation command is an instruction command transmitted when an abnormality occurs in the pachinko machine 10. In this specific example, the command is based on the E1 error code of 70H01H, the E2 error code of 70H02H, and the E3 error code of 70H03H. It is configured.
In this specific example, the E1 error code is a ten-count abnormal error and is output when no game ball is detected when the special winning opening 40 is opened, and the E2 error code is a switch when the lower plate 23 is full and the tank is full. The E3 error code is output when the supply switch 44 is turned on. The error message displayed by transmitting these abnormal-time commands is erased by the 70H04H error release code transmitted when the abnormality is cleared.

In the subsequent output processes (step S60), the main control board 30 includes a special symbol display device 32, a prize ball control board 31, a launch control board 33, a lamp control board 34, and a sound control board according to the progress of the game. 35, big winning opening solenoid 40
Output processing is performed for each of the various solenoids such as c. That is, when it is detected by each of the input processes (step S45) that a game ball is won at each winning port on the game board 22, the prize ball control board 31 pays out the game ball as a prize ball. A process of outputting data, a process of outputting sound data corresponding to a game state to the sound control board 35, and an error signal to the symbol control board 32b in order to notify that an error has occurred when the pachinko machine 10 has an abnormality. The output process is executed, and the jackpot process is executed when a jackpot occurs.

The remaining process following the above-described process is composed of an out-of-design symbol random number updating process (step S65) and an initial random number updating process (step S70), and is exactly the same as the above-described steps S20 and S35, respectively. is there. These two processes form an infinite loop and are repeatedly executed as long as time permits until the next interrupt is executed. The time required to execute this processing from step S10 to S60 described above differs for each interruption depending on whether the big hit processing is executed, a difference in a special symbol display mode, and the like. As a result, the number of times the residual process is executed also differs for each interrupt, and the updated (added) values of the out-of-design symbol random number and the initial random number are not uniform by executing the interrupt process shown in FIG. 5 once. Disappears. This eliminates the possibility that the initial random number and the out-of-design symbol random number are synchronized with the pass / fail random number. In this embodiment, since the update of the random number is changed by the value of the initial random number, there is no possibility of synchronization. Further, the above-described ordinary symbol random number updating process (step S40) may be configured to be executed in the remaining process.

During the game, the above-mentioned prize ball control board 3
1. The control executed by the lamp control board 34, the sound control board 35, and the like has the same configuration as that of the related art, and a description thereof will be omitted.

(Probability Change and Time Saving Processing of First Example) Next, the probability change and time reduction processing of the first example executed by the main control board 30 will be described with reference to FIGS. First, the subroutine of the probability variation control will be described with reference to FIG. It is determined whether or not the display result of the special symbol change is a big hit (S110). If a big hit is determined in S110, it is next determined whether or not the big hit symbol is a positively changing symbol (S1).
20). If it is determined in S120 that the symbol is a probable variable design,
The probable change flag J is set (S130) and the process returns. On the other hand, if it is determined in S110 that the display result of the special symbol change is not a big hit, and if it is determined in S120 that the symbol is a normal symbol other than the positively-variable symbol, the process directly returns to the return.

Next, a subroutine of the probability improvement period control 1 executed by the main control board 30 will be described with reference to FIG. First, it is determined whether the big hit operation has been completed (S210). When it is determined in S210 that the big hit operation has been completed, it is determined whether or not the probable change flag J is set (S220). When the probability change flag J is set, the jackpot lottery is set to a high probability (S230).
Thereby, the jackpot lottery is performed with each change operation of the special symbol in a state where the probability of the jackpot lottery is set to a high probability. Next, it is determined whether or not the special symbol has fluctuated, that is, whether or not there is a hold storage, or whether or not the first-type start-up switch 36a has been turned on (S240). If there is a pending memory,
Or, at least, if the first-type starting port switch 36a is turned on, the special symbol is changed. If it is detected in S240 that the special symbol has changed, the positive change counter G indicating the number of positive changes is incremented by +1 and stored in the memory (S250). "The probability change is later XX times" is displayed and the player is notified of the number of times the special symbol has changed (the number of starts) in the probability change (S260). Subsequently, it is determined whether or not the probability change counter G has reached 50 times (S270). If the probability change counter G does not reach 50, the process returns. If it is determined in S270 that the probability variation counter G has reached 50 times, the probability variation operation is terminated, the probability variation flag J is reset (S280), the probability variation counter G is set to 0 (S290), and the big hit is reached. The lottery is set to a low probability (S295), and the process returns to the return. Note that S2
If a negative determination is made in 10, S220, and S240, the process directly returns to the return.

Next, the subroutine of the time reduction control 1 executed by the main control board 30 will be described with reference to FIG. First, it is determined whether or not the jackpot operation has been completed (S
310). If it is determined in S310 that the big hit operation has been completed, it is determined whether or not the probability change flag J is set (S320). If the probable change flag J is set, the time reduction period flag K is set (S330), and the time reduction operation is performed (S340). This time-saving operation shortens the change time of the special symbol to speed up the determination of the special symbol, and also shortens the change time of the normal symbol to increase the chances of winning a prize in the ordinary electric accessory 36. Next, it is determined whether or not the special symbol has fluctuated, that is, whether or not there is a hold storage, or whether or not the first-type start-up switch 36a is turned on (S3).
50). The special symbol is changed if the first-type start-up switch 36a is turned on if there is a hold memory or even without it.
When it is detected in S350 that the special symbol has changed, the time saving variation counter H indicating the number of time saving variations is incremented by +1 and stored in the memory (S360). "Time savings will be XX times later" is displayed, and the player is notified of the number of times the special symbol has changed (the number of starts) during the time savings (S370).
Subsequently, it is determined whether or not the time reduction counter H has reached 100 times (S380). If the time reduction counter H does not reach 100, the process returns. When the time reduction counter H has reached 100 times, the time reduction operation is stopped by resetting the time reduction period flag K (S390), and the time reduction counter H is set to 0 (S390).
395), exit to return. Note that S310 and S32
0, if a negative determination is made in S350, the process directly returns to the return.

An example of the above-described probability change control, probability improvement period control 1 and time reduction period control 1 will be described with reference to the time chart of FIG. In FIG. 12, first, the LCD 32a
When the big hit symbol of the probability symbol is derived in each of the special symbol display areas 50a to 50c, a probability improvement period is generated accordingly, and the period continues until the special symbol changes to 50 times, and the high probability state is maintained. , And the period ends when it reaches 50 times. On the other hand, with the start of the probability improvement period, a time reduction period also occurs, and the period is continued until the special symbol changes to 100 times, and the time reduction operation is executed, and when the change reaches 100 times, the period ends.

If a big hit state occurs due to the stoppage of the change of the special symbol during the probability improvement period or the time reduction period, the big hit operation is prioritized, and the high probability operation and the time reduction operation executed during the period are stopped. It is good also as a state. In the case of a big win with a probability variable symbol again during the probability improvement period or the time reduction period, the probability variation counter G or the time reduction counter H is reset, and after the big hit operation is completed, it is counted from the beginning, which is advantageous to the player. Processing can also be performed. In addition, when a large hit is made with a symbol that is not a probability variable symbol, it is possible to continue the remaining number of times of the variable probability counter G and the time reduction counter H after the big hit is completed. Is also possible.

As described above, in the present specific example 1, when the big hit operation with the probable change symbol ends, the probabilistic change control is provided in the probability improvement period, and the time reduction operation in the time reduction period whose end is longer than the probability improvement period. And granting. For this reason, in the past, the probability change and the time saving were completed at the same time, but in the present embodiment, since the time saving period is set even after the probability improvement period is completed, it is necessary to maintain and improve gambling. Can be. In addition, the probability improvement period and the shortening period are both defined by the number of times of the special symbol change, and even if the jackpot is derived or continues to be derived during the probability improvement period in a symbol other than the probability variation symbol, the probability improvement period and the reduction period are There is an effect to be secured.

(Probability Change and Time Saving Process of Second Specific Example) Next, the probability change and time reduction process of the second specific example executed by the main control board 30 will be described with reference to FIGS. Since the subroutine of the probability variation control in FIG. 9 and the subroutine of the probability improvement period control 1 in FIG. 10 are the same, they will be referred to, so that the subroutine of the time reduction period control 2 executed by the main control board 30 will be described. 13 will be described. First, it is determined whether the big hit operation has been completed (S410). If it is determined in S410 that the big hit operation has been completed, it is determined whether or not the probability change flag J has changed from the set state to the reset state (S420). When the probable change flag J is reset, the time reduction period flag K is set (S430), and the time reduction operation is performed (S440). This time-saving operation shortens the change time of the special symbol to speed up the determination of the special symbol, and also shortens the change time of the normal symbol to increase the chances of winning a prize in the ordinary electric accessory 36. Next, it is determined whether or not the special symbol has fluctuated, that is, whether or not there is a hold storage, or whether or not the first-type start-up switch 36a has been turned on (S450). The special symbol is changed if the first-type start-up switch 36a is turned on if there is a hold memory or even without it. If it is detected in S450 that the special symbol has changed, the time reduction counter H is incremented by +1.
Increment and memorize it in the memory (S460), and display "the number of times of change due to time saving is H times" and "the number of times of time saving is XX times later" on the background screen 52, and display to the player the number of times the special symbol changes during time saving (Starting frequency) is notified (S470). Subsequently, it is determined whether or not the time reduction counter H has reached 50 times (S480). If the time reduction counter H does not reach 50 times, the process returns to the return. When the time reduction counter H has reached 50 times, the time reduction operation is terminated by resetting the time reduction period flag K to stop the time reduction operation (S490), and setting the time reduction counter H to 0 (S495). Exit on return.

An example of the above-described probability change control, probability improvement period control, and shortened period control 2 will be described with reference to the time chart of FIG. In FIG. 14, first, when the big hit symbol of the probability symbol is derived in each of the special symbol display areas 50a to 50c of the LCD 32a, a probability improvement period occurs with this, and the variation of the special symbol becomes 50 times until the special symbol changes to 50 times. The period continues and the state becomes a high probability state, and when the number of times reaches 50, the period ends.
On the other hand, with the end of the period, a time reduction period occurs, and the period is continued until the special symbol changes to 50 times, and the time reduction operation is executed. When the change reaches 50 times, the period ends.

As described above, in the present specific example 2, when the jackpot operation with the probable variable symbol ends, the probabilistic change control in the probability improvement period is given first, and after the probability improvement period ends, the time reduction in the predetermined time reduction period is performed. An action is given. For this reason, conventionally,
At the same time, the probable change and the time saving ended, but in the present embodiment, the time saving period is set after the probability improvement period ends by shifting the time saving period after the probability improvement period. Pleasure can be set aside, time savings can be enjoyed following the probability improvement period, and gambling can be maintained and improved. On the other hand, there is also an effect that a profit can be secured for the hall because the time reduction is regulated.

(Probability Change and Time Saving Process of Third Example) Next, the probability change and time reduction process of the third example executed by the main control board 30 will be described with reference to FIGS. The subroutine of the probability variation control is the same as that of FIG. Next, a subroutine of the probability improvement period control 3 executed by the main control board 30 will be described with reference to FIG. This process is substantially the same as the probability improvement period control 1 in FIG. 10, and therefore, the description of the common part will be referred to, but the difference is that the variable probability counter G is compared with 120 in S570.

Next, the subroutine of the time reduction control 3 executed by the main control board 30 will be described with reference to FIG. This processing is substantially the same as that of the time-saving period control 1 in FIG.
When the time reduction counter H is 0, the time reduction counter H is compared with a predetermined range (the time reduction counter H is in the range of 30 to 60 or 90 to 120). After S680, the time reduction stop processing (S68)
When performing 5) and making a negative determination in S680, a step in which the time reduction counter H is compared with 170 (S68).
7) is different.

An example of the above-described probability change control, probability improvement period control 3 and time reduction period control 3 will be described with reference to the time chart of FIG. In FIG. 17, first, the LCD 32a
When the big hit symbol of the probability symbol is derived in each of the special symbol display areas 50a to 50c, a probability improvement period is generated accordingly, and the period continues until the special symbol changes to 120 times, and the high probability state is maintained. And the period ends at 120 times. On the other hand, with the start of the probability improvement period, a time reduction period also occurs, and the period is continued until the special symbol changes to 30 times, and the time reduction operation is performed. Thereafter, the time reduction period is stopped for 30 times, The time-saving operation is performed 30 times again with the time-saving period set, and the time-saving operation is again set 30 times and the time-saving operation is stopped.
For the zero time, a time saving period is set and the time saving operation is executed.

As described above, in the present specific example 3, when the jackpot operation with the probable change symbol is completed, the probabilistic control is provided in the probability improvement period, and the intermittent operation is performed intermittently in the shortening period longer than the probability improvement period. Time saving operation is provided. For this reason, in the past, the probable change and the time saving ended at the same time, but in the present embodiment, the time saving operation is performed intermittently even during the probability improvement period, and intermittently even after the probability improvement period ends. Since the time reduction period is set, gambling can be maintained and improved. On the other hand, the hole also has the effect that profits can be secured because the time reduction period is intermittently regulated.

(Probability Change and Time Saving Process of Fourth Specific Example) Next, a description will be given with reference to the probability change and time reduction process of the fourth specific example executed by the main control board 30.

This process is the same as the second embodiment except that the probability improvement period and the shortening period are interchanged. The flowchart can be created by a person skilled in the art from FIGS. 9, 10, and 13. Invite examples.

An example of the above-described probability change control, probability improvement period control, and shortened period control will be described with reference to the time chart of FIG. In FIG. 19, first, when the big hit symbol of the probability symbol is derived in each of the special symbol display areas 50a to 50c of the LCD 32a, a time-saving period is generated, and the period is changed until the special symbol changes 50 times. Continue and the state becomes a high probability state, and the period ends when the number of times reaches 50.
On the other hand, when the period ends, a probability improvement period occurs, and the probability improvement operation is continuously performed until the number of special symbol changes reaches 50 times, and the period ends when the change reaches 50 times. I do.

As described above, in the fifth embodiment, when the big hit operation with the probable variable symbol ends, a time-saving operation is first given in the time-saving period, and after the time-saving period ends, the probability improvement in a predetermined probability improvement period is given. An action is given. For this reason, conventionally,
At the same time, the probability change and the time saving were ended, but in the present embodiment, the probability improvement period is set after the time reduction period by shifting the probability improvement period after the time reduction period. Can be set aside later, the probability fluctuation can be enjoyed continuously within a short time, and the gambling can be maintained and improved. On the other hand, since the probability improvement period is also regulated for the hall, there is an effect that profit can be secured.

(Probability Variation and Time Saving Process of Sixth Specific Example) Next, the probability variation and time saving process of the sixth specific example executed by the main control board 30 will be described. This processing is the same as the third example except that the probability improvement period and the shortening period are exchanged. The flowchart can be created by those skilled in the art from FIGS. 9, 15, and 16. Three specific examples are cited.

An example of the above-described probability change control, probability improvement period control, and shortened period control will be described with reference to the time chart of FIG. In FIG. 20, first, when a big hit symbol of a probability symbol is derived in each of the special symbol display areas 50a to 50c of the LCD 32a, a time-saving period is generated, and the period is reduced until the special symbol changes to 120 times. Continues, the time saving operation is performed, and the period ends when it reaches 120 times. On the other hand, with the start of the short time period, a probability improvement period also occurs, and the period continues until the special symbol changes to 30 times, and the jackpot lottery is set to a high probability, and thereafter, the probability improvement period is 30 times. Is stopped, the jackpot lottery is set to low probability, the jackpot lottery is set again to high probability for 30 times, and the probability improvement period is stopped again for 30 times, and the jackpot lottery is set to low probability, and 5 more at the end
Zero times, a probability improvement period is set, and the jackpot lottery is set to a high probability.

As described above, in the present specific example 6, when the big hit operation with the probable variable symbol ends, the time saving operation is given in the time saving period, and the probability improvement period is intermittently performed in the period that is longer than the time saving period. , The jackpot lottery is set to a high probability state. For this reason, in the past, the probability change and the time saving ended at the same time, but in the present embodiment, the probability improvement operation is performed intermittently even during the time saving period,
Since the probability improvement period is set even after the time reduction period ends, the gambling can be maintained and improved. on the other hand,
Since the probability improvement period is intermittently regulated also for the hall, there is an effect that the profit can be secured.

(Operation of the present embodiment) The pachinko machine 10 executes the following operations by executing the above-described processes. That is, a game ball is fired on the game board 22 by the firing motor 33a in accordance with the amount of rotation of the firing handle 24 operated by the player, and the fired game ball is an ordinary electric accessory 36 as a first-type starting port. Is won by the first-type start-up switch 36a, and the special symbol display device 3
2 special symbol display areas 50a-5 on the LCD 32a screen
At 0c (see FIG. 6), the special symbol fluctuates and is displayed for a predetermined period of time, followed by static display. Commands relating to symbols are transmitted from the main control board 30 to the symbol control board 32b, and the symbol control board 32b determines the occurrence of reach as described above, and displays images such as special symbols and background symbols on the LCD 32a screen. The image control is performed as described above. As for the special symbol, the left symbol is displayed statically first, then the right symbol is statically displayed, and if the right symbol does not match the left symbol, the departure is determined, and then the middle symbol is statically displayed. If the right symbol and the left symbol match (for example, 7-7), it will be reach,
The still image is displayed after the middle symbol fluctuates. If the middle symbol that has been statically displayed does not match the right and left symbols, the reach is lost (for example, 727). On the other hand, when the special symbol that is statically displayed is a predetermined specific symbol, for example, when all the special symbols match after the reach (3777 such as “777”)
When the same digit is displayed, a big hit state is displayed.
Provide advantageous game content to the player. As described above, whether or not the big hit state occurs depends on whether or not the value of the random number determined when the game ball is detected by the main control board 30 by the first-type start-up switch 36a is a predetermined value. It is determined. Whether or not to reach is determined by the symbol control board 32b depending on whether or not the value of the reach determination random number is a determination value.

When the big hit state is reached, the special winning opening 4
0 is released for about 30 seconds or until the count switch 40b detects that 10 game balls have been won, whichever comes first. At this time, the game balls that have won in the special winning opening 40 pass through the special area. V switch 4
Once detected as 0a, the special winning opening 40 is closed and then opened again, and this opening operation is repeated up to 16 times. Normally, 15 game balls are paid out as prize balls for one game ball winning. Therefore, when one big hit state occurs, about 2400 (= 15 × 10 × 1)
6) A plurality of game balls can be obtained as prize balls. The prize ball discharging operation is executed by the prize ball control board 31. still,
V solenoid 40d that opens and closes the special area of the special winning opening 40
Is for closing the special area when one game ball passes through the special area. Thereafter, when the big hit operation is completed, the probable change operation and the time saving operation as described in the specific examples 1 to 3 are executed.

(Effects of the present embodiment) According to the present embodiment described in detail above, by making the probability improvement period different from the time reduction period, it is possible to realize a game having a configuration which has not existed in the past, and to improve the probability. It is possible to improve the relationship between the period and the time and short-term, and improve the taste. Also, even after the end of the probability improvement period, by providing the privilege of shortening the time, the player will not be bored.On the other hand, even after the end of the short period of time, by providing the benefit of the probability improvement period, the player will not be bored. In addition, it is possible to avoid a situation in which the probability improvement period or the shortened time period ends early, and to give a player a period more than a certain period, which is advantageous to the player, thereby giving a sense of security to the player. In addition, by using those periods as the basis of the number of times the special symbol changes, there is an effect that the player can easily give an indication of the end of the period. Furthermore, by setting the probability improvement period or the shortening period to be an intermittent period, even if the player thinks that the probability improvement period or the reduction period has ended, it is possible to enhance the interest of the game by reviving the period. effective. On the other hand, since the probability improvement period or the time period can also be regulated for the hall, there is an effect that the profit can be secured.

The present invention is not limited to the specific examples described above, and it goes without saying that the present invention can be modified within the intended range of the present invention. For example, in the above-described embodiment, the normal symbol is shortened to facilitate the start winning prize to the ordinary electric accessory 36. However, other procedures, for example, the probability of hitting the ordinary symbol during the time reduction is increased. For example, the normal electric accessory 36 is opened a plurality of times for one start winning, the opening time is extended, or a combination thereof is used. Even in this case, the start winning is extremely likely to occur.

In this embodiment, the special symbol is shortened so that the determination of the special symbol is hastened. However, another procedure may be used. For example, instead of sequentially stopping the special symbol, three symbols are simultaneously stopped. Thus, the fluctuation time can be reduced. Even if the reach action is abolished or the time shortened, the time saving effect can be realized. If all the special symbols during the probability change have no reach action, a simple display is obtained, and the next big hit symbol can be quickly acquired. Various types of probability fluctuations are possible, such as a once-continuous type, a two-time type, and an upper-limit number-restricted type (the maximum number of hit operations is limited even if the probability change symbol is drawn again during the probability change) after the probability fluctuation enters. . In the present embodiment, the probable change symbol also serves as the big hit symbol, but may be set separately.
